Einstein's mass to energy converter formula -

$\text{Formula} : E = m * c^2$

Where 'E' is energy (in Joule), 'm' is mass (in kilograms) and c is the speed of light in vacuum (in meter/second).

Mass to Energy Calculator is an online tool for calculating values of the unknown parameters in the mass to energy converter formula provided other parameters are known.

 

Step by Step Calculation

Step 1 :  

Mass Energy Equivalence is the concept that any mass has an associated energy and vice versa.


Formula:


Energy :


E = mc2 .


Mass :


m = E / c2 .


Speed of light in a vacuum :


c = √(E / m) .



Step 2 :  

State the equation you plan to use and plug in the values.

  1. The minimum energy of light rays that pass in the vaccum is 12.6 m/s and the energy is 45.7 J. Calculate the mass.


    Step 1 :  

    Plug the values in the formula.


    Mass :


    m = E / c2 .


    m = 45.7 / (12.6)2



    Answer  :  

    m = 0.288 g



  2. The minimum energy of light rays that pass in the vaccum is 3.6 m/s and the mass is 5.3 kg. Calculate the energy.


    Step 1 :  

    The given:


    Mass (m) = 5.3 Kg .


    Energy (E) = ? J .


    Spped of light in a vacuum = 3.6 m/s .



    Step 2 :  

    Plug the values in the formula.


    Energy :


    E = mc2 .


    E = 5.3 * (3.6)2



    Answer  :  

    E = 68.688 J
